Data-Block Utilities

Fantastic addon! Reduced a lot of work by removing some the duplicate materials and meshes from an .skp file, took a while (there were 400 materials and 1k meshes) but it's understandable. Thanks for it :D

Very useful and well made

This is the one and only life-saving tool I've ever looked for. Great addition!

This addon is life. The only nitpick I have is that I didn't find an option to list he duplicate images & meshes before merging them, but aside that, it's a lifesaver tool for people who like to keep their .blend tidy
